The Apg4b is a cysteine protease and a member of the autophagin protein family. This enzyme cleaves the C-terminal sequences of the precursor forms of Apg8 proteins (including GABARAP, GATE16 and MAP-LC3), and regulates the lipidation and delipidation processes of these proteins. This specific cleavage reveals the conserved C-terminal glycine present in mature and active forms of the Apg8 proteins that are conjugated to phosphatidylethanolamine (PE) during autophagy.
